Title (EN) IN-SITU CATALYST AND MOISTURE GENERATION FOR CROSSLINKING OF SILANE-FUNCTIONALIZED POLYOLEFINS
(FR) CATALYSEUR IN SITU ET GÉNÉRATION D'HUMIDITÉ POUR LA RÉTICULATION DE POLYOLÉFINES FONCTIONNALISÉES AU SILANE
Abstract:
(EN) Ethylene-vinylsilane polymers are cured under ambient conditions using a pre-catalyst mixture of an organotin, e.g., dibutyltin oxide (DBTO), and a carboxylic acid, e.g., stearic acid. The mixture generates a catalyst in-situ as well as water, and thus minimizes or eliminates the requirement for diffusion of moisture from the environment into the bulk polymer.
(FR) Selon la présente invention, des polymères d'éthylène vinyl-silane sont durcis dans des conditions ambiantes au moyen d'un mélange de pré-catalyseur constitué d'organotine, par exemple d'oxyde de dibutyltine (DBTO), et d'acide carboxylique, par exemple d'acide stéarique. Le mélange génère un catalyseur in situ et de l'eau, et permet donc de réduire ou d'éliminer la nécessité de diffuser de l'humidité depuis l'environnement à destination du polymère en vrac.
